Improved washing-machine



To all whom it may concern can infin/eo Letters Patent lvm-94,938, dated September 21,1869.

IMPRovED WASHING-MACHINE.

The Schedule referred to in thse Letters Patent and making part of the same.

Beit known that I, GEORGE W. BENTON, of East Pike, in the county of Wyoming, and State of New York, have invented certain new and useful Improvements in Washing-Machines; and I do hereby declare that the following is a full'and exact descriptionthereof, reference being had to the accompanying drawings, in which- Figure I is `a longitudinal vertical section.

Figure II, a pla-u thereof.

Like letters of reference designate like parts in eachofthe figures. i

My improvements relate to that class of washingmachines in which the, washing is effected by a ribbed cylinder oscillating on a concave of rollers, arranged side by side, between which'an'd the said cylinder the clothes are placed, and moved back and forth, as required by the action of the cylinder. lhe rollers forming the concave have heretofore been arranged in a frame fitting within the box or tub forming the body of the machine, and been supported on two ellpticsprings.

My invention consists- First,fof the special device, constructed 4as/herein-` after described, forming adjustable spring bearings for the journals of the oscillating cylinder. Second, in supporting the fra'me containing the concave onfour spiral springs, arranged around suitable guidelpins under each corner, in combination with the cylinder and its adjustable spring bearings.'

In the drawingsi f A is the rectangular 'box or tub for containing the water,rsupported on suitable legs, B B, and forming' the frame for supporting the cylinder C, the journals of which are retained in notches in the sides thereof.

D D is a'series. of rollers, arranged side .b vside under the cylinder, and within the rectangular frame E E, forming the concave before alluded to.

fj' are guide-pins, projecting. upward from the. b0t.

tom of the box A, through the spiral springs g g, and

. the frame E, which is supported on the latter.

The cylinder O, I prefer to construct as shown, consisting of the shaft H,V two head-blocks, I,.of semi- `cylindrical form, as shown in Fig. I, sufficient space being left between them for the free water.

K is the winch or arm, the cylinder. v

Al l are two rods, which hook over the. ends `of the journals, and thence descend outside of the box, passing through the stationary guide-piece m, and follower or movable piece n, Where they are fastened by thumbscrews c.

passage of the at one end, for oscillating The cross-pieces m a are secured between two uprights, 1) p, fastened to the lower portion of the tub, and lto a cross-piece, R, connecting the two legs ofthe machine. lhe ends of the movable piece n fit in slots in the u'pljghts, so as to haveafree vertical movement therein. Y,

From 4this cross-piece two pins, r, extend upward, passing'loosely through the stationary cross-piece m and interposed spiral springs's.

lhe thumb-screw o permits the cylinder to be adj usted so as to press with greater or less force on the concave, according to the thickness of the garments being washed. I

The 4spiral springs under the frame of. the concave, in connection with the upper spring bearingsof the cylinder', enable the parts to yield with the greatest facility to the inequalities ofthe clothes interposed between th`eni'. lhisenables the machine to be more easily operated, and subjects it to less wear and strain,

andpreserves the clothes' from injury 'in the breaking parts are made less yielding.

I do not claim, broadly, a yielding concave, or a' yielding andadjustable pressure-cylinder; but- What I claim as my invention, and desire to secure The arrangementwith the concave D, ribbed cylinV der' 0, frame E, and tub A, of the 'adjusting-screw o, rod l, spiral springs s g, and'gude-pins r f, as herein set forth.
